Should i watch it?

ロスト is definitely a "One of a kind" show. i've never seen Supernatural, but if あなた like to think and analyze problems, ロスト is the 表示する for you. I've watched the entire series twice, and it still amazes me. Hope this helps あなた with your decision.

I don't even know how to try to describe Lost...there hasn't ever been a 表示する like it. OUaT comes the closest because they're the same writers BUT it's not the same 表示する At ALL. So, if あなた like OUaT, there's a good chance you'll like Lost.
And, in my personal opinion, ロスト is worth watching just for Sayid ;D

スーパーナチュラル is my お気に入り 表示する ever! It's about family, what real ヒーローズ look like and - gah, it's too hard for me to explain! Though, this 表示する can be scary at times and there's blood and stuff if that bothers you.

Oh goodness, just try them out and fangirl with me XD
